ABSTRACT:
The present invention relates to polyorganosilylated carboxylate monomers or polymers thereof, comprising a polyorganosilylated carboxylate monomer of the general formula (I) or a polymer thereof,wherein R1, R2, R3, R4, R5each independently represent hydrogen, alkyl, alkenyl, alkynyl, alkyloxy, aryl, aralkyl or halogen radical optionally substituted by one or more substituents independently selected from the group comprising alkyl, aralkyl, aryl, hydroxy, halogen, amino or amino alkyl radicals,R7represents hydrogen, alkyl radical or —COOR9, wherein R9represents an alkyl group,R8represents hydrogen, alkyl radical or —CH2—CO2—(SiR4R5O)n—SiR1R2R3, andn represents a number of dihydrocarbylsiloxane units from 3 to 20.The invention also relates to the use of these monomers or polymers as coating compositions including antifouling coating compositions.
